SynonymsFST; FS
DescriptionFollistatin-like 1 (FSL1 or FSTL1), also known as FRP (follistatin-related protein), Flik (follistatin-like), and TSC36 (TGFβ1stimulated clone 36), is a secreted 45-55 kDa extracellular glycoprotein belonging to the BM40/ SPARC/Osteonectin family. The human FSTL1 cDNA encodes 308 amino acids (aa), including a 20 aa signal sequence, a cysteinerich Follistatin (EGF and kazal-like) domain, two apparently non-functional EF hand calciumbinding motifs, and a von Willebrand Factor C homology domain. Mature human FSTL1 shares 94%, 95%, 98%, and 99% aa identity with mouse, rat, bovine, and equine FSTL1, respectively. FSTL1 was first identified as a TGF-beta-induced protein from a mouse osteoblast cell line (4). It is ubiquitously expressed in early mouse development, but is mainly mesenchymal later in development. In humans, FSTL1 is a common rheumatoid arthritis autoantigen. It is reported to be either proinflammatory due to promoting inflammatory cytokine secretion, or to prevent autoimmune arthritis by inhibiting matrix metalloproteinase (MMP) and prostaglandin expression. In muscle and heart, it appears to be protective and promotes endothelial cell functions such as revascularization after ischemia, probably due to promoting expression and activation of the protein kinase AKT1.
